Join Britain's much-admired monarch on one of her rare days-off, as she and her loveable pet corgi Mr Brown enjoy an action packed adventure at London's Natural History Museum. On a grey, gloomy and unbearably miserable day, the two friends go in search of dinosaurs. Armed with sandwiches and biscuits they encounter immense skeletons, huge teeth and a thigh bone as big as the Queen. There are aliens from outer space and some smelly dinosaur dung too! After much exploring it is no surprise when they both fall asleep - which is when the real excitement begins! Find out what really happened to the dinosaurs all those years ago, what the Queen is doing on top of a Megalosaurus and who wins a famous victory. Beautifully illustrated and affectionately told, the book is great to read aloud and is also highly suited to encourage children to read on their own. With lots of facts about how dinosaurs lived and why they all disappeared, this is a delightful tale of two close friends and their eventful day at the Museum.
